Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and in particular to a multifunctional transfer and lifting device. Background Technology

[0002] In the manufacturing process, for lifting operations involving large and heavy goods, the relevant technologies generally employ equipment such as overhead cranes and mobile forklifts within the factory to handle and lift the goods.

[0003] However, the overhead crane for lifting operations inside the factory can only be used within the factory's operating range. It cannot be used for lifting operations that cross factory buildings or are outside the factory.

[0004] If a mobile forklift is used for handling and lifting operations, there are several drawbacks. The equipment cost of a mobile forklift is relatively high, and operators need to obtain relevant certifications to perform handling and lifting operations. In addition, mobile forklifts are generally large and require a large working space, making them unsuitable for lifting operations in small spaces. Furthermore, in related technologies, the insertion direction of mobile forklifts is parallel to the forklift's forward direction, which makes them unsuitable for insertion operations in right-angled spaces. Therefore, there are areas for improvement. Summary of the Invention

[0005] To accommodate material lifting operations requiring more workspace, this application provides a multi-functional transfer and lifting device.

[0006] The multifunctional transfer and lifting device provided in this application adopts the following technical solution:

[0007] A multi-functional transfer and lifting device includes a frame, an internal lifting mechanism, a detachable support unit that engages with the material to support the material at the bottom, and a detachable counterweight at the bottom of the frame below the support unit to ensure the balance of the frame.

[0008] The direction of the insertion and support of the support unit and the material can be adjusted to be parallel or perpendicular to the width direction of the frame.

[0009] The bottom of the frame, on the side away from the counterweight, is equipped with transfer wheels.

[0010] By adopting the above technical solution, in actual use, the lifting mechanism can be used to lift the supporting unit, and the entire frame can be transported as a whole through the transfer wheels at the bottom, which is convenient and quick to operate.

[0011] In addition, since the insertion direction of the support unit and the material can be adjusted to be parallel or perpendicular to the width of the frame, in practical applications, operators can set the support unit to two insertion states according to the working space, and then adjust the insertion state according to the working space to adapt to the working environment under the constraints of horizontal and vertical space.

[0012] Preferably, the frame body has mounting slots on both sides in the width direction to accommodate different installation heights.

[0013] By adopting the above technical solution, and utilizing the assembly slots on both sides of the frame width direction that can be adapted to different installation heights, the frame can be assembled onto other fixed objects, providing the other fixed objects with the function of lifting materials. The frame can also be assembled and fixed onto the production line, serving as a module on the production line that requires lifting functions, thereby realizing multiple application scenarios.

[0014] Preferably, the supporting unit includes a mounting base that is detachably coupled with the lifting mechanism and two adjustable supporting forks mounted on the mounting base. The adjustment direction of any of the supporting forks can be set to be parallel or perpendicular to the width direction of the frame.

[0015] By adopting the above technical solution, when actually adjusting the insertion direction of the support unit, it is only necessary to adjust and install the support forks to complete the adjustment of the insertion direction of the entire support unit.

[0016] Preferably, the supporting unit further includes a limiting plate that is detachably fixed on one side of the two supporting forks in the horizontal direction opposite to each other, and the opposite sides of the two limiting plates respectively form an abutment clamp with the two sides in the width direction of the material.

[0017] By adopting the above technical solution, two limiting plates can be used to abut against the outer side of the material in the width direction, thereby improving the stability of the material lifting operation.

[0018] Preferably, the lifting mechanism includes a drive motor, a lifting screw, and a lifting seat. The drive motor is installed inside the frame, the lifting screw is vertically rotatable inside the frame, the output shaft of the drive motor and the lifting screw form a transmission connection, the lifting seat is threadedly connected to the lifting screw, the lifting seat is vertically slidable inside the frame via a guide rail, and the mounting base is detachably installed on the lifting seat.

[0019] By adopting the above technical solution, during actual lifting operations, the rotation of the drive motor drives the rotation of the lifting screw, thereby achieving the lifting adjustment of the lifting seat under the action of the guide rails on both sides of the lifting seat.

[0020] Preferably, the frame includes symmetrically spaced assembly side frames, a front cover plate and a rear cover plate installed on the front and rear sides of the two assembly side frames, and an upper top plate and a lower bottom plate installed on the upper and lower sides of the two assembly side frames. The lifting mechanism is located between the two assembly side frames, the supporting unit is located on one side of the front cover plate, and the front cover plate has a clearance groove for avoiding the connection between the lifting seat and the mounting base. The upper part of the rear cover plate is provided with an operating handle seat.

[0021] By adopting the above technical solution, the entire frame is made into a cuboid structure, and the lifting mechanism is set between the two assembly side frames. While maintaining a small thickness, the internal space of the frame is fully utilized. In actual use, the frame can also be laid flat in a horizontal state, in which case materials can be transported horizontally. In this state, the operating handle seat serves as both an operating handle and a support seat for the rear cover plate. That is, with the help of the operating handle seat and the transfer wheels, the frame can be supported as a whole, enabling it to have the function of horizontal transportation.

[0022] Preferably, the frame body is also provided with a displacement sensor for detecting the position of the lifting seat, the front cover plate is provided with a detection sensor for detecting the loading height of the material, and the frame body is also provided with an alarm, a drive button group for controlling the operation of the drive motor and a controller, and the displacement sensor, detection sensor, alarm, drive button group and controller are electrically connected.

[0023] By adopting the above technical solution, in actual use, the displacement sensor can detect the displacement of the lifting seat and thus realize point control of the material lifting movement. At the same time, the detection sensor on the front cover plate can detect the full load height of the lifted material and transmit the material loading height data to the drive motor through the controller, thereby accurately controlling the lifting amount and loading amount of the material.

[0024] Preferably, the detection sensor is adjustablely mounted on the front cover plate along the height direction of the material loading.

[0025] By adopting the above technical solution, the detection sensor can be adjusted and installed on the front cover plate along the height direction of the material loading, thereby adjusting and detecting the full load height of the material.

[0026] Preferably, the lifting seat has an upward-opening mounting groove, and the mounting base has a downward-facing insertion block that engages with the mounting groove. The insertion block and the mounting base form an abutment groove that opens downward and fits into the outer wall of the mounting groove.

[0027] The lower base plate has an embedding groove, which is oriented towards the side of the supporting unit. The counterweight and the embedding groove are interlocked. A rotating rod is rotatably mounted on the lower base plate. One end of the rotating rod is provided with an insertion pin that interlocks with the counterweight. The insertion direction of the insertion pin is perpendicular to the insertion direction of the counterweight. The other end of the rotating rod is provided with a foot pedal.

[0028] By adopting the above technical solution, during actual disassembly and installation of the base, the upward-opening mounting slot, plug-in block, and abutment slot enable quick installation of the base. Operators simply need to insert the plug-in block on the base downwards into the mounting slot on the lifting seat.

[0029] In addition, when actually disassembling and installing the counterweight, the operator only needs to step on the foot pedal to drive the other end of the rotating rod to tilt upwards until it is detached from the counterweight. After that, the operator only needs to drive the frame backwards, and the counterweight will stay in place due to its own weight, thus completing the quick disassembly and installation of the counterweight.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By utilizing the support unit whose insertion and support direction with the material can be adjusted to be parallel or perpendicular to the width of the frame, lifting operations can be achieved in more working spaces;

[0032] 2. By using displacement sensors, detection sensors, controllers, and drive button sets, automated material lifting operations can be achieved. In addition, the lifting amount of materials can be precisely controlled by detecting the height of the lifting platform and the full load height of the materials.

[0033] 3. The counterweight can be quickly disassembled and reassembled by means of a pin, a rotating rod and a foot pedal. At the same time, the mounting slot and pin block on the lifting seat can be used to quickly install the mounting base and the lifting seat. This installation method can also improve the load-bearing capacity of the support unit. Attached Figure Description

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0044] This application discloses a multifunctional transfer and lifting device.

[0045] Example 1

[0046] Reference Figure 1 and Figure 2 The multi-functional transfer and lifting equipment includes a frame 1, a lifting mechanism 2 is installed inside the frame 1, and a support unit 3 is installed on the front side of the frame 1 to form an insertion fit with the material so as to support the material at the bottom. The support unit 3 is detachably fixedly connected to the lifting mechanism 2. The insertion support direction of the support unit 3 and the material can be adjusted to be parallel or perpendicular to the width direction of the frame 1.

[0047] Reference Figure 1 and Figure 2 The bottom of the frame 1 is detachably equipped with a counterweight 4 to ensure the balance of the frame 1. The counterweight 4 and the support unit 3 are located on the same side of the frame 1. Two transfer wheels 5 are symmetrically arranged on the bottom of the frame 1 away from the counterweight 4. Two operating handle seats 6 are arranged above the transfer wheels 5 on the frame 1.

[0048] In actual use, the operator can easily move the frame 1 to the required working environment using the operating handle seat 6 and the transfer wheel 5. In addition, the operator can adjust the insertion support direction of the support unit 3 to be parallel or perpendicular to the width direction of the frame 1 according to the working space environment, so that it can be used for insertion operations under right-angle space constraints, and thus be applicable to more working environments.

[0049] Reference Figure 1 and Figure 2 The frame 1 includes symmetrically spaced assembly side frames 11, front cover plates 12 and rear cover plates 13 installed on the front and rear sides of the two assembly side frames 11, and upper top plates 14 and lower bottom plates 15 installed on the upper and lower sides of the two assembly side frames 11. That is, the frame 1 is in the shape of a cuboid.

[0050] Reference Figure 1 and Figure 3 The lifting mechanism 2 includes a drive motor 21, a lifting screw 22, and a lifting seat 23. The drive motor 21 is vertically mounted on the lower side of the top plate 14 of the frame 1. A first pulley 211 is coaxially fixed on the output shaft of the drive motor 21. The two ends of the lifting screw 22 in the length direction are respectively rotatably mounted on the upper top plate 14 and the lower bottom plate 15 through bearings. A second pulley 221 is coaxially fixed on the upper end of the lifting screw 22 in the vertical direction. A transmission belt 222 is sleeved on the first pulley 211 and the second pulley 221, thereby realizing the transmission connection between the drive motor 21 and the lifting screw 22.

[0051] Reference Figure 1 and Figure 3The lifting seat 23 is threadedly connected to the lifting screw 22. The two ends of the lifting seat 23 in the length direction are vertically slidably mounted on the two assembly side frames 11 through guide rails. That is, since the lifting screw 22 is used for lifting transmission, the overall thickness of the frame 1 can be set to be smaller, thereby further reducing the space occupied by the equipment during operation.

[0052] Reference Figure 1 and Figure 3 The lifting seat 23 is fixedly provided with two extended connectors 231 at intervals. The supporting unit 3 and the two extended connectors 231 on the lifting seat 23 form a detachable fixed connection. On the front cover plate 12 of the frame 1, corresponding to the positions of the two extended connectors 231, two strip-shaped clearance grooves 121 are opened along the lifting direction of the supporting unit 3 to avoid the two extended connectors 231.

[0053] Reference Figure 1 and Figure 3 The support unit 3 includes a mounting base 31 and two adjustable support forks 32 mounted on the mounting base 31. In this embodiment, the mounting base 31 includes a detachable mounting part 311 and an adjustable mounting part 312. The mounting base 31 includes two plate structures, one of which is a straight plate structure. The detachable mounting part 311 and the adjustable mounting part 312 of this plate structure are respectively arranged on both sides in the thickness direction. The detachable mounting part 311 of the mounting base 31 of the straight plate structure is detachably mounted on the extended connector 231 by bolts.

[0054] Reference Figure 3 and Figure 4 Another type of plate structure for mounting base 31 is an L-shaped plate structure. The detachable mounting part 311 and the adjustable mounting part 312 of this plate structure are respectively provided on both sides of the thickness direction, and the detachable mounting part 311 and the adjustable mounting part 312 are respectively on the two right-angled sides of the plate structure. The adjustable mounting part 312 of this plate structure is set perpendicular to the front cover plate 12 of the frame 1. The detachable mounting part 311 of this plate structure is also detachably connected to the extended connector 231 by bolts.

[0055] Reference Figure 4 and Figure 5 The L-shaped plate structure also allows the right-angled side perpendicular to the front cover plate 12 to be located on the left or right side of the front cover plate 12 of the frame 1, forming a left-side or right-side insertion support operation.

[0056] Reference Figure 1 and Figure 4Since the connection relationship between the adjusting mounting part 312 of the two plate-type structures of the mounting base 31 and any supporting fork 32 is the same, the connection relationship between the adjusting mounting part 312 of one plate-type structure and any supporting fork 32 will be described as an example.

[0057] Reference Figure 1 and Figure 4 Each of the supporting forks 32 has an integrally formed clamp block 321 with a notch at one end along its length. The clamp block 321 is clamped on the adjusting mounting part 312, and a spring pin 3211 is provided on the clamp block 321. Correspondingly, the adjusting mounting part 312 of the mounting base 31 has multiple spring pins 3211 along its length to form a pin groove for insertion and engagement, thereby realizing the adjustable installation of the supporting fork 32 on the adjusting mounting part 312.

[0058] Reference Figure 1 and Figure 4 The supporting unit 3 also includes a limiting plate 33 that is detachably fixed to one side of the two supporting forks 32 in the horizontal direction by bolts. The end of the limiting plate 33 facing away from the front cover plate 12 is provided with a guide surface 331. Thus, the opposite sides of the two limiting plates 33 form abutment clamps with the two sides of the material width direction to improve the stability of the material during the lifting process.

[0059] Reference Figure 1 and Figure 3 A displacement sensor 7 is installed at the top inside the side frame 11. The displacement sensor 7 detects the displacement of the sliders on both sides of the lifting seat 23 along the length direction, thereby detecting the lifting height of the lifting seat 23. An adjustment groove 122 is provided in the middle of the front cover plate 12 of the frame 1 along the lifting direction of the material. An installation seat 8 is detachably connected to the adjustment groove 122 by bolts. A detection sensor 81 is installed on the installation seat 8. By detecting the height of the detection sensor 81, it can be used to detect the full load height of different materials.

[0060] Reference Figure 1 and Figure 3 The frame 1 is also equipped with an alarm 9 and a controller 10. A drive button assembly 20 is installed on one side of the frame 1 where the side frame 11 is mounted. The drive button assembly 20 includes a lifting button, a lowering button, and an emergency stop button. The displacement sensor 7, detection sensor 81, alarm 9, drive button assembly 20, and controller 10 are electrically connected. Thus, the operator can automatically drive the lifting seat 23 via the drive button assembly 20.

[0061] Reference Figure 1 and Figure 3One side of the counterweight 4 is fixed to the lower base plate 15 by bolts, thereby realizing the detachable installation of the counterweight 4. The structure of the counterweight 4 can be set as a single support structure. The single support structure is located below the middle of the two supporting forks 32. In this single support structure, the middle of the two rows of wheels of the wheel pallet extends into the pallet. In addition, for the wheel pallet, the two supporting forks 32 of this embodiment extend from the middle of the two rows of wheels to support it. The ends of the two supporting forks 32 away from the frame 1 are provided with guide slopes 322. The included angle formed by the two guide slopes 322 is set at an acute angle, which faces the front cover plate 12 of the frame 1.

[0062] Reference Figure 4 and Figure 5 The counterweight 4 can also be configured as a double support structure, the width of which is greater than or equal to the maximum distance between the two telescopic forks.

[0063] Reference Figure 6 For this type of counterweight 4 structure, the corresponding straight plate mounting base 31 can be set to be longer so as to be used for inserting and supporting pallets with a large width.

[0064] The implementation principle of a multifunctional transfer and lifting device according to an embodiment of this application is as follows:

[0065] In actual use, operators can easily move the frame 1 to the required working environment using the operating handle seat 6 and the transfer wheels 5. In addition, operators can adjust the insertion support direction of the support unit 3 to be parallel or perpendicular to the width direction of the frame 1 according to the working space environment. Specifically, by selecting different plate structure mounting bases 31, both positive insertion support operation and side insertion support operation can be completed. The side insertion type can also be set to left side insertion and right side insertion, thus making it suitable for insertion operations under right angle space constraints, and thus applicable to more working environments.

[0066] Example 2

[0067] Reference Figure 7 The difference between this embodiment and Embodiment 1 is that...

[0068] Both assembly side frames 11 are provided with multiple elongated assembly slots 111. The length direction of any assembly slot 111 is parallel to the lifting direction of the material. In this embodiment, the frame 1 can be adapted to different installation heights by means of the assembly slots 111. Then, the operator can assemble the frame 1 onto other fixed objects to add the function of lifting materials to other fixed objects. The frame 1 can also be assembled and fixed on the production line to serve as a module on the production line that needs to perform lifting functions, thereby realizing multiple application scenarios.

[0069] Example 3

[0070] Reference Figure 8 The difference between this embodiment and Embodiment 1 or 2 is that...

[0071] The outer connecting body 231 of the lifting seat 23 has an upward-opening mounting groove 2311. On any plate-shaped mounting base 31, a plug-in block 313 is provided downward at its detachable mounting part 311 to form a plug-in engagement with the mounting groove 2311. The plug-in block 313 and the mounting base 31 form an abutment groove 314 with an downward opening and an embedded engagement with the outer wall of the mounting groove 2311. In actual disassembly and assembly, the operator only needs to move the mounting base 31 to a certain height and then lower the mounting base 31 so that the plug-in block 313 is inserted into the mounting groove 2311 to complete the overall installation of the support unit 3.

[0072] The lower base plate 15 has an embedding groove 151 along the horizontal direction towards the supporting unit 3. The counterweight 4 has an insertion part 41, which forms an insertion fit with the embedding groove 151. The rear cover plate 13 of the frame 1 has a stepping space. The lower base plate 15 is located in the stepping space and is connected to a rotating rod 30 by a torsion spring. One end of the rotating rod 30 is provided with a foot pedal 301, and the other end is provided with an insertion pin 302. The lower base plate 15 has a guide hole 151 that forms a guide fit with the insertion pin 302. Correspondingly, the counterweight 4 has an insertion hole 42 in the insertion part 41 that forms an insertion fit with the insertion pin 302. The insertion pin 302 passes through the guide hole 151 and is inserted into the insertion hole 42.

[0073] When actually disassembling and installing the counterweight 4, the operator only needs to step on the foot pedal 301 to drive the other end of the rotating rod 30 to tilt upwards until the insertion pin 302 disengages from the insertion hole 42. After that, the operator only needs to use the operating handle seat 6 to drive the frame 1 backwards. The counterweight 4 will stay in place due to its own weight, thus completing the quick disassembly of the counterweight 4.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
